What is BPD?

Borderline personality disorder (BPD) is a serious mental health condition characterized by chronic emotion dysregulation that affects how people think, feel, and connect with others. Often misunderstood, it touches millions of lives worldwide, impacting individuals as well as entire families and communities.

Common Features of BPD

  • Intense, rapidly changing emotions
  • Challenges in relationships and trust
  • Deep fear of abandonment
  • Impulsivity or self-harming behaviors
  • Difficulty coping with stress and anger

The Truth About BPD

  • More common than rheumatoid arthritis, celiac disease, and autism spectrum disorder
  • Affects an estimated 1.6% of adults in the U.S.
  • Ripple effects extend to 5–7% of families nationwide
  • Scientists agree that BPD develops through a complex interaction of biological vulnerability and life experience. There is no single cause — and no single path to recovery.
